Message:

Regarding FTP Client

Posted by Varun Gupta on September 05, 2001 at 2:00 AM

Hi Srinivas Parvath ,

This is a nice code you have written and very helpful too but i have a problem. How can we specify that how many directories are avaliable on the FTP Server and how can we choose in which directory tp upload our files.

Moreover javadocs for this package are not avaliable. Where can i get them.

Thanks
Varun...
